* Add leaflet_method decorator

This allows javascript method calls to be generated using
an empty method body and a signature. Useful for writing plugins.

As an example (and the driving motivation) I implemented this on
the geoman plugin.

* Fix tests

* Implement all useful leaflet methods on geoman

Only the free modules for now

* Add a snapshot test

Update README to point to the extra plugin

Bump actions/setup-python from 4 to 5 in the github-actions group

* Add code coverage to test runs

* Fix for issue 1359

This includes a structural change. I added a Class object with
a include method. This follows leaflet's `L.Class.include`
statement. This allows users to override Leaflet class behavior.

The motivating example for this can be found in the added
`test_include` in `test_map.py`. Using an include, users can
override the `createTile` method of `L.TileLayer` and add
a headers.

* Close #1359

Add an include statement, that will allow users to override
specific methods at Leaflet level. This allows users to customize
the "createTile" method using a JsCode object.

* Add documentation
